目的 评价微波肝切除治疗原发性肝癌的效果．方法 对６７例原发性肝癌随机分为两组。一组采用微波肝切除术３１例；另一组采用常规肝切除术３６例作为对照．结果 微波肝切除组术后１、３、５年生存率分别为９０．３％（２８／３１）、４９．４％（１５／３１）、２９．０％（９／３１）；常规肝切除组术后１、３、５年生存率分别为８８．９％（３２／３６）、４３．９％（１６／３６）、２５．０％（９／３６）。两组生存率差异无显著性意义（Ｐ＞０．０５）．然而，微波肝切除组术中平均失血量仅３８２．２ｍｌ（２８０～８７０ｍｌ），低于常规肝切除组的平均失血量５９６．５ｍｌ（４１０～１６６０ｍｌ），微波肝切除术的１、３、５年复发率是３．０％（１／３１）、２５．８％（８／３１）、４１．９（１３／３１）也低于常规肝切除术１、３、５年复发率的１１．１％（４／３６）、３８．９％（１４／３６）、５８． ９％（２１／３６）。结论 微波肝切除术失血量少，对肝功能影响小，复发率代，是原发性肝病一种有效的治疗方法。
Objective To evaluate the effect of microwave hepatectomy on primary liver cancer. Methods 67 cases of primary liver cancer were randomly divided into two groups. One group used microwave hepatectomy in 31 cases; the other group used conventional hepatectomy in 36 cases as a control. RESULTS: The 1-, 3-, and 5-year survival rates in the microwave liver resection group were 90.3% (28/31), 49.4% (15/31), and 29.0% (9/31), respectively; routine hepatectomy The 1-, 3-, and 5-year survival rates were 88.9% (32/36), 43.9% (16/36), and 25.0% (9/36), respectively. There was no significant difference in survival rate between the two groups (P>0.05). However, the mean blood loss in the microwave liver resection group was only 382.2 ml (280-870 ml), which was lower than the average blood loss of the regular liver resection group (596.5 ml, 410-1660 ml). The 1, 3, and 5 of the microwave hepatectomy The annual recurrence rate was 3.1% (1/31), 25.8% (8/31), and 41.9 (13/31) were also lower than the recurrence rate of conventional liver resection at 1, 3 and 5 years. 1% (4/36), 38.9% (14/36), 58. 9% (21/36). Conclusion Microwave hepatectomy has less blood loss, little effect on liver function, and relapse rate, which is an effective treatment for primary liver disease.
